WLTPStandards

WLTPStandards refers to the Worldwide Harmonised Light Vehicles Test Procedure, an internationally agreed-upon set of rules and regulations for testing the emissions and fuel consumption of passenger cars and light commercial vehicles. It was developed by the United Nations Economic Commission for Europe (UNECE) and aims to provide a more realistic and globally harmonised measurement of vehicle performance compared to previous, often country-specific, testing cycles. The WLTP was implemented in stages, with different regions adopting it at various times. The procedure involves a standardised test cycle that simulates driving conditions more accurately, including variations in speed, acceleration, and deceleration, as well as different road types and ambient temperatures. This results in fuel consumption and CO2 emission figures that are generally higher than those reported under older, less stringent test cycles like the New European Driving Cycle (NEDC). The WLTP also includes tests for other pollutants, such as nitrogen oxides (NOx) and particulate matter. Its primary goal is to ensure a level playing field for manufacturers worldwide and to provide consumers with more accurate and comparable information about a vehicle's environmental impact.
